"Unlimited" should be banned from advertising slogans. It's like an "all you can eat" buffet that kicks out the customers that eat too much. It's a trick that companies employ because nobody reads their TOCs that let them kick out power users. It's misleading advertising. Why not promise people 100TB of storage? Because then you'd actually have to live up to your promises. Since living up to promises of "unlimited" data isn't feasible, this strategy should be banned. Same goes for Yahoo! Mail and their "unlimited" storage.
